A refreshed 13-inch MacBook Air has been leaked and it includes a new Broadwell chip from Intel. Chinese site Feng shows Apple is upgrading the Air with Broadwell but is changing very little overall. The refresh appears to have a 1.6 GHz 5250U processor, 4 GB of RAM, and HD Graphics 6000.

This is only the lowest-end model but the changes will scale-up with upgraded versions of the MacBook Air.

Apple may talk about some refreshed laptops during its March 9 event.
